    Lupin is an Andean legume with great nutritional potential. The lack of alternatives to its traditional use represents a challenge for large-scale lupin oil production due to the absence of standardized parameters in the extraction process. The study aimed to analyze the operating parameters that influence the yield and composition of lupin (Lupinus mutabilis sweet) oil. A methodology was used that included mechanical extraction at two different ratios using the Flora Power equipment to evaluate yield under different humidity conditions, gas chromatography for the analysis of fatty acid composition, and the oxidative rancidity test in Oxitest to establish the oil's shelf life. The results revealed that Treatment 2 was the most efficient, achieving the highest oil yield under conditions of lower seed moisture and greater equipment efficiency in the extraction process. The lipid profile of the oil showed a high content of unsaturated fatty acids, particularly oleic acid. The shelf life ranges from 10 to 13 days without any refining process. Research highlights the cardiovascular health benefits conferred by the high concentration of monounsaturated fatty acids, thus contributing to a product with promising nutritional and functional characteristics for the market.
